<<-EOS
This version of GDAL was built with Python support. In addition to providing
modules that makes GDAL functions available to Python scripts, the Python
binding provides ~18 additional command line tools.
Unless you are using Homebrew's Python, both the bindings and the
additional tools will be unusable unless the following directory is added to
the PYTHONPATH:
#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages
